bearing shoot
1.2. The effect of green cover on vine growth and developmentThere were no significant differences in phenological phase of Cabernet Sauvignonbetween treatments, but the rate of bud germinating percentage, bearing shoot percentage, fruit set percentage, fruiting coefficient（bunch/shoot）of vines and yield of grape berry were reduced significantly.
3.The short shoot leaves had higher assimilating efficiency with the 5th leaf(from top end to basic) of the Starkrimson new and the leaves on new shoot having the maximal net photosynthetic assimilation rate(Pn=15.39mg CO_2·dm~(-2)·h~(-1)). This is one of the physiologicl bases for the early bearing and high yielding spur type apple.
